problems with my passenger side blinkers?

Hi. I Have a 94 Ford Explorer and I'm having problems with my passenger side blinkers. When I turn my right side blinker on the front one won't come on and the back one stays on, won't blink. And my dash light won't come on either. But all the lights work when I use my flashers. I had a mouse live in the truck, able to get into the cab from behind the ashtray somewhere, could the mouse have chewed through the wiring? If so songs that have screwed up my flashers as well? Please help me in being able to fix it because I don't want to get a ticket because of it. Thanks!
